Nissan Rogue (T33) 2021-Present Service Manual: Its Can Communication 2 Circuit

Diagnosis Procedure

CHECK CAN DIAGNOSIS

Check the CAN diagnosis results from CONSULT to see that the ITS CAN communication 1 circuit and ITS CAN communication 4 circuit have no malfunction.

Are the ITS CAN communication 1 circuit and ITS CAN communication 4 circuit normal?

GO TO 2.

Check and repair ITS CAN communication 1 circuit and/or ITS CAN communication 4 circuit.

CONNECTOR INSPECTION

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect all the control unit connectors on ITS CAN communication 2 circuit.

4. Check the terminals and connectors for damage, bend and loose connection.

Is the inspection result normal?

GO TO 3.

Repair the terminal and connector.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Check the continuity between the ADAS control unit 2 harness connector and front camera unit harness connector.

• Without ProPILOT Assist 2.1

  ADAS control unit 2 harness connector		Front camera unit harness connector		Continuity
  Connector No.	Terminal No.	Connector No.	Terminal No.
  B4	34	R17	7	Existed
  	35		3	Existed

• With ProPILOT Assist 2.1

  ADAS control unit 2 harness connector		Front camera unit harness connector		Continuity
  Connector No.	Terminal No.	Connector No.	Terminal No.
  B135	4	B141	7	Existed
  	24		3	Existed

Is the inspection result normal?

GO TO 4.

Check the harness and repair or replace the root cause.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the ADAS control unit 2 harness connector terminals.

• Without ProPILOT Assist 2.1

  ADAS control unit 2 harness connector			Continuity
  Connector No.	Terminal No.
  B4	34	35	Not existed

• With ProPILOT Assist 2.1

  ADAS control unit 2 harness connector			Continuity
  Connector No.	Terminal No.
  B135	4	24	Not existed

Is the inspection result normal?

GO TO 5.

Check the harness and repair or replace the root cause.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the ADAS control unit 2 and the ground.

• Without ProPILOT Assist 2.1

  ADAS control unit 2 harness connector		Ground	Continuity
  Connector No.	Terminal No.
  B4	34		Not existed
  	35		Not existed

• With ProPILOT Assist 2.1

  ADAS control unit 2 harness connector		Ground	Continuity
  Connector No.	Terminal No.
  B135	4		Not existed
  	24		Not existed

Is the inspection result normal?

GO TO 6.

Check the harness and repair or replace (if shield line is short) the root cause.

CHECK ADAS CONTROL UNIT 2 AND DISTANCE SENSOR TERMINATION CIRCUIT

1. Remove the ADAS control unit 2 and the distance sensor.

2. Check the resistance between the ADAS control unit 2 terminals.

   • Without ProPILOT Assist 2.1

     ADAS control unit 2		Resistance (Ω)
     Terminal No.
     34	35	Approx. 108 – 132

   • With ProPILOT Assist 2.1

     ADAS control unit 2		Resistance (Ω)
     Terminal No.
     4	24	Approx. 108 – 132

3. Check the resistance between the distance sensor terminals.

   Distance sensor		Resistance (Ω)
   Terminal No.
   3	2	Approx. 108 – 132

Is the measurement value within the specification?

GO TO 7.

Replace the front camera unit and/or the distance sensor.

CHECK SYMPTOM

Connect all the connectors. Check if the symptoms described in the “Symptom (Results from interview with customer)” are reproduced.

Inspection result

GO TO 8.

Start the diagnosis again. Follow the trouble diagnosis procedure when past error is detected.

CHECK UNIT REPRODUCTION

Perform the reproduction test as per the following procedure for each unit.

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect one of the unit connectors of ITS CAN communication 2 circuit.

   NOTE:

   ADAS control unit and distance sensor have a termination circuits. Check other units first.

4. Connect the battery cable to the negative terminal. Check if the symptoms described in the “Symptom (Results from interview with customer)” are reproduced.

   NOTE:

   Although unit-related error symptoms occur, do not confuse them with other symptoms.

Inspection result

Connect the connector. Check other units as per the above procedure.

Replace the unit whose connector was disconnected.
